GPIO0 26 I/O High Z CMOS/ 2X General Purpose I/O
GPIO4 7 I/O High Z CMOS/ 2X General Purpose I/O
All digital I/Os comply with 3 volts CMOS.
Both GPIO0 and GPIO4 are low level at reset.
You can access (write or read) the GPIO value via AT+WIOW and AT+WIOR commands. See the AT
commands Interface Guide documentation
[7] for more details.
3.11 Analog to Digital Converter (ADC)
An Analog to Digital Converter is provided by the Integra M2106+ Wireless CPU
®
. This converter is 10-bit
resolution, ranging from 0 to 2.8 V. You can see the measurements via the AT+ADC command. See the AT
commands Interface Guide documentation
